Q&A: How to converter RealView scripts to Lauterbach CMM scripts for mx53

[#1]

Q:

Does anyone have the Lauterbach script files for connecting to the mx53?  Also,  does anyone know of a converter to convert RealView scripts to Lauterbach?

A:

Please see below attach.cmm and load_simbols.cmm for i.MX53.
